The effect of cold aqueous extract of lemon peel against types of bacteria isolated from the cooling devices Filters

Abstract

The antibacterial effect of citrus peel lemon against the bacterial strains obtained from the filtersof air conditioners have been selected based on the presence most in these filters such asStreptococcus, Bacillus spp, Pseudomonas, E coli. agar well diffusion method used to evaluateantibacterial activity of citrus peels water extract. through the results became clear to us that thecold aqueous extract of lemon peel showed a significant effect on the growth of bacterial speciesthrough the diameters of inhibition zone that appeared in all concentrations of the extract (125,250, 500, 1000) mg/ml. Gram-positive bacteria Streptococcus spp were the most affected Wherethe diameters of inhibition zone (18, 15, 12, 0, 0) mm respectively, while The Gram-negativebacteria E coli least affected. The results obtained in this study indicate that citrus lemon peel canbe used in the treatment of diseases caused by organisms for the purposes of the pharmaceutical.
